That depeds in your budget.... if you are going for everything top of the line the 2Gbs should be pretty useful for some of the most demanding games out there... OTOH, if you are going for a more budget minded PC 1 GB should be enough for the moment... it all depends on what are you goint to buy, otherwise the 2 Gb would be overkill in most situations.

BTW, 512kB is about 1/3 of a floppy

I think you mean 512 MB sticks. My first computer carried 512 kB sticks in it, but I bet you won't run any recent programs on it.

If you really want to game, get 2GB. Otherwise, get 1 GB as with normal windows programs, you won't notice the difference. You do notice a difference with certain games though (bf2 comes to mind). If you can choose between value 2 GB or overclockers 1 GB, I'd favour the value ram...

I guess if I'm spending all this money I might aswell spend a bit more and get the 1GB sticks. I mean if sticks of 1GB are going to improve performance overall then I should get them, right?

That's what it comes down to in the end - PERFORMANCE

I'll most likely be getting a DFI lanparty nf4 SLI-DR. I know it is quite picky about its RAM. I've hear that Corsair are a no no for this mobo. And that OCZ are a good choice. What about Kingston? If 4x512MB are gonna get me better performance than 2x1GB sticks then I'll get the 512 sticks. What do you think?

The latencies of single sticks may be generally lower on 512 MB sticks but with the 4 sticks of 512 you'll take a latency hit having so many sticks anyways that it would at least cancel out. Thatll leave some expansion room for more ram if the need arises in a year or two, not that the rest of the components would be up to par...

I see your logic! Next thing for me is to work out which 1GB sticks I should go for! If the diff in performance is negligable between an expensive stick of ram and one a little less pricey, then I would probably get the cheaper one and put more money into the g-card or on other things.

The only brands that seem to be sold in this country are Corsair, OCZ and Kingston. Corsair has been said to be a bad choice if I get a DFI lanparty nf4 SLI-DR. So I guess that leaves me with OCZ and Kingston.

(if you're interested in seeing what limited choice we get in this country then here you go:
